Image Preview Guidelines
You can preview your scanned image so you can adjust the scan settings using the preview as a guide.
There are two types of preview available, depending on the scan mode and selected settings:
Thumbnail preview
A thumbnail preview displays your previewed images as thumbnails with the scanned image area and
exposure automatically selected. If the Thumbnail checkbox is selected, clicking the Preview button
opens a thumbnail preview.
Normal preview
A normal preview displays your previewed images in their entirety so you can select the scanned
image area and other settings manually. If the Thumbnail checkbox is deselected, clicking the
Preview button opens a normal preview.

Scan Resolution Guidelines
If you plan to enlarge a scanned image so you can print it at a larger size, you may need to increase the
resolution from the default resolution set by EPSON Scan. Follow these guidelines to determine the
resolution setting you need:
• You will enlarge the image as you scan it.
If you will enlarge the image using EPSON Scan's Target Size setting (Home and Professional modes
only), you do not need to increase the Resolution setting.
• You will scan the image at its original size, but enlarge it later in an image-editing program.
Increase EPSON Scan's Resolution setting in your scan. Increase the resolution by the same amount
you will increase the image size to retain a high image quality. For example, if the resolution is 300 dpi
(dots per inch) and you will double the image size later, change the Resolution setting to 600 dpi.
• You will scan the image at 100% or smaller size.
Select EPSON Scan's Resolution setting based on how you will use the scanned image:
• E-mail/view on a computer screen/post on the web: 96 to 150 dpi
• Print/convert to editable text (OCR): 300 dpi
• Fax: 200 dpi
